Android Date and Time Format internationalization implementation code

In multi-language versions, the date and time format is a headache. Fortunately, Android provides DateFormate, which can be formatted Based on the default format of the specified language region.

Directly paste the Code:

Copy codeThe Code is as follows: public static CharSequence formatTimeInListForOverSeaUser (

Final Context context, final long time, final boolean simple,

Locale locale ){

Final GregorianCalendar now = new GregorianCalendar ();

// Special time

If (time <MILLSECONDS_OF_HOUR ){

Return "";

}

// Today

Final GregorianCalendar today = new GregorianCalendar (

Now. get (GregorianCalendar. YEAR ),

Now. get (GregorianCalendar. MONTH ),

Now. get (GregorianCalendar. DAY_OF_MONTH ));

Final long in24 H = time-today. getTimeInMillis ();

If (in24 h> 0 & in24 H <= MILLSECONDS_OF_DAY ){

Java. text. DateFormat df = java. text. DateFormat. getTimeInstance (

Java. text. DateFormat. SHORT, locale );

Return "" + df. format (time );

}

// Yesterday

Final long in48 H = time-today. getTimeInMillis () + MILLSECONDS_OF_DAY;

If (in48 h> 0 & in48 H <= MILLSECONDS_OF_DAY ){

Return simple? Context. getString (R. string. fmt_pre_yesterday)

: Context. getString (R. string. fmt_pre_yesterday)

+ ""

+ Java. text. DateFormat. getTimeInstance (

Java. text. DateFormat. SHORT, locale). format (

Time );

}

Final GregorianCalendar target = new GregorianCalendar ();

Target. setTimeInMillis (time );

// Same week

If (now. get (GregorianCalendar. YEAR) = target

. Get (GregorianCalendar. YEAR)

& Now. get (GregorianCalendar. WEEK_OF_YEAR) = target

. Get (GregorianCalendar. WEEK_OF_YEAR )){

Java. text. SimpleDateFormat sdf = new java. text. SimpleDateFormat ("E", locale );

Final String dow = "" + sdf. format (time );

Return simple? Dow: dow

+ Java. text. DateFormat. getTimeInstance (

Java. text. DateFormat. SHORT, locale). format (time );

}

// Same year

If (now. get (GregorianCalendar. YEAR) = target

. Get (GregorianCalendar. YEAR )){

Return simple? Java. text. DateFormat. getDateInstance (

Java. text. DateFormat. SHORT, locale). format (time)

: Java. text. DateFormat. getDateTimeInstance (

Java. text. DateFormat. SHORT,

Java. text. DateFormat. SHORT, locale). format (time );

}

Return simple? Java. text. DateFormat. getDateInstance (

Java. text. DateFormat. SHORT, locale). format (time)

: Java. text. DateFormat. getDateTimeInstance (

Java. text. DateFormat. SHORT, java. text. DateFormat. SHORT,

Locale). format (time );

}

Note that java. text. DateFormat is used here, and another java. text. format. DateFormat is used. The latter cannot specify locale.
